FAUC ET.

SPECIFICATION forming part of Letters Patent No. 248,971, dated November` 1, 1881,

Application tiled June 8, 1881. (No model.)

To all whom 'it may concern Be it known that I, CHARLES WniT'rAKnR, a citizen ofthe United States, residing at the city of Chicago, in the county .o t' Cook and State of Illinois, have-invented certain new and usei'ul Improvements in Faucets; and I do hereby declare the l'ollowing to be a full, clear, and exact description of the invent-ion., such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters or ligures marked thereon, which form a part ot' this specification.

My invention relates to improvements in that class of faucets which are adapted to be connected with both hot and cold water pipes, and by which the hot and cold water may be mingled togetherl in equal portions or in any proportions desired bet'ore escaping, and by which either the hot or cold water may be drawn separately. An index-plate is provided, which shows the proper place to adjust the handle, whereby the temperature ot' the stream may be known without testing the same.

My invention is vfurther explained by reference to the accompanyingdrawings,in which- Figure 1 represents a vertical section drawn on line or as of Fig. 3. Fig. 2 is a side view ot' the cam. Fig.3i1s a horizontal section. Fig. 4 is a top view. Fig. 5 is a side view.

A is the valve-chamber.

B is the hot-water inlet, which is provided with stopper C.

D is the cold-water inlet7 which is provided with stopper E. The stoppers C and E are respectively provided with valve-rods F and Gr. Ways H H are formed upon the respective sides ot' the chamber for the reception of the slides I I. rIhe slides I I are moved upward and downward by cam J, whereby the respective hot and cold water passages are opened and closed. The cam J is rigidly secured to the stem M, and is moved with it as the handle N is moved.

O is the index-plate, upon which the words Hot,77 Cold, Mediumjl and Stop are written, thus indicating the proper places of adjust.- ing the handle to produce the results thus indicated.

The Stoppers are formed of rubber or other elastic substances in the ordinary manner.

The case or chamber A may be cast in a single piece, and the cover or index plate O secured thereto by a screw-joint, as shown.

That portion ot the cam J between 1 and 2 55 forms a true horizontal plane which extends at right angles to the vertical stem M. The part between 2 and 3 and l and 3, respectively,'in, clines do wnward, forming an obtuse angle from the highest to the lowest point in the cam.

As thus far described, my invention is substantially like my previous invention,t`or which application t'or Letters Patent of the United States was tiled April I2, 1881.

My improvements upon said previous invention consist in substituting the simple cam J for the two cams previously used; also, in the peculiar construction ot' said cam and ot' the peculiar relative arrangement of the slides and stoppers to said cam, whereby a singlecam 7o will perform all and the same functions which in my said previous device required two cams. This end is accomplished by forming about onethird of the area ot' said cam J, consisting ofv that part between l and 3 and 2 and 3, upon 75 ditt'erent inclined planes, as shown bythe dotted lines in Fig. 2, and by locating the hot and cold water valves both upon one side of the center, as seen in Figs. 3 and 4, whereby both valve-slides may simultaneously rest upon the 8o horizontal portion of said cam,- and both stop pers be thereby retained in a' closed position at the same time.

My invention consists,further, in providing the respective slides l I with anti-friction rollers b b b b, between which the earn J movesas the handle is turned. Also, in providing the spout IJ and the tube It, respectively, with" stop-cocks S and T, by which stop-cocks the course of the water may be readily changed. 9o When the stop-cock S is closed therwater will iiow through tube It. When stop-cool; T is closed and stop-cockS is opened the water will take the ordinary course through the spout. The words Hot77 and Cold are located one 95 side ot' the center, conforming to the change of position of the hot and cold water valves.

My faucet is operated as follows: NVhen the handle N is moved to the word Hot77 the slide I is moved downward by the cam J, whereby 1o@ the hot-water valve C is opened, while the slide I is simultaneously acted upon by thc opposite side ofthe catn and moved in the opposite direction, whereby the cold-water valve E is closed. When the handle is moved from the word Hot to Stop;7 the upward incline of cam J, acting upon the slide I, draws the stopper C upward and closes the hot-water valve, while the-horizontal portion of said cam moves through the slide I without changing its level, while it retains the stopper unmoved in its closed position. Thus both passages are closed and the flow of water stopped. When the handle is moved on from the word Stop 7 to the word Cold the horizontal portion of cam J, between l and 2, moves through the recess in slide I without changing its position, and it retains the stopper C nnmoved in its closed position, while the angular portion of' said cam acts upon slide I, forcing it downward, whereby the cold-water valve or stopper Eis opened. When the handle is moved on from Cold7 to Medium the. respective slides are acted upon bythe incline portion of the cam, and are both thereby simultaneously thrown halfway open, whereby the hot and cold water is mingled together in equal proportiotis.

It is obvious that by moving the handle from the word Medium toward the word Hot the hot-water valve will be thrown more widely open, while the cold-water valve will be partially closed, whereby an excess of hot water is caused to ilow. Also, that when the handle is inversely moved from the word Medium toward the word Cold the opposite result is produced. Thus it is obvious that the flow of water from the faucet may be readily gratluated from cold to hot 0r from hot to cold to any temperature desired.

Having thus described my invention, whatI claim a-s new, antl desire to secure by Letters Patent, iS-

1. In a hot and cold water graduating fancet, the cam J, forming three distinct planes, one horizontal and two inclined, conversely arranged, as connected with the handle and the hot and cold water valves or Stoppers, said cam being adapted to move said Stoppers both simultaneously and alternately in opposite directions or retain them both at the same time itl a closed position, as set fort-h.

2. In a hot and cold water graduating faucet, the combination ofthe case A, upwardlyextending tube It, spoilt P, stop-cocks S and T, said stop-cocks being adapted to change the course of the stream from a downward to an upward direction or inversely in the opposite direction, as desired, substantially as and for the purpose set forth.

3. In faucets, the combination of the slides I I, anti-friction rollers b b b b, and cam J, slibstanti-ally as set forth.

4. In a hot and cold watt-r graduating faucet, the combination of indcx-plate O, having the words Hot 7 and Cold piinted thereon, both at one side of the center above the respective hot and cold water valves, stem M, handle N, cam J, slides` I I, valve-rods F and G, stoppers B and E, all substantially as and for the purpose set forth.

In testimony whereof I atix my signature in presence. of two witnesses.

CHARLES WHI'ITAKER.
